Description
The Atmel AT75C310 Smart Internet Appliance Processor (SIAP) is a high-perfor-
mance processor specially designed for Internet appliance applications, such as
Internet telephony (Voice over Internet Protocol VoIP). The AT75C310 is built
around an ARM7TDMI microcontroller core running at 20 MIPS with two DSP co-pro-
cessors running at 40 MIPS each all three processors delivering unmatched
performance for low power consumption.
In a typical standalone VoIP phone, one DSP handles the voice-processing functions
(voice compression, acoustic echo cancellation, etc.), while the other one deals with
the telephony functions (dialing, line echo cancellation, callerID detection, high-speed
modem, etc.). In such an application, the power of the ARM7TDMI allows it to run the
VoIP protocol stack as well as all the system control tasks.
Atmel provides the AT75C310 with three levels of software modules:
a special port of the Linux kernel as the proposed operating system
a comprehensive set of tunable DSP algorithms for modems and voice processing,
specially tailored to be run by the DSP subsystems
a broad range of application-level software modules such as H323 telephony or
POP-3/SMTP e-mail services
